Remy has been diagnosed with stage 2-3 LP in his right rear leg. It arose from a jumping related injury some months ago. It is surprising because after his injury he had full hip and leg xrays taken by his first vet, and I (purposefully) switched vets at that point, took his xrays to his NOW current vet and had him examined for a second opinion. My one question was whether he had LP or not. BOTH said no at that point in time. Currently he is lifting his leg and is occasionally lame, the vet says it is NOW LP

The vet is Falls Road Animal Hospital and while they are highly regarded, I really want a second opinion.
Any LP specialists or orthro specialist recommendations would be appreciated.
